MECHANICAL MOVEMENT.

Be it known that I, HULDii-Eiori EGLI, a cit-V izen of Switzerland, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements inMechanical Movements; andk I do hereby declare the following to be a full, clear, and

exact'V description ofthe same, reference i V being had lto the accompanying drawings,

' ingmilk bottles to and removing said bottles vforn'iing'part of this specification.

The present invention relates to 'improvements in mechanical movements, and more j particularly to means for imparting a reciprocatory motion to a4 feeding mechanism such, for instance,l as 'amechanism for feedfrom'their respective jets in a bottle washing apparatus, although other forms of feed-l ing mechanisms may well be provided with the present` invention without departing from the spirit thereof.

Anfobject of the present invention'is to yprovide a rocker cam that will have a com-- v 'pajratively long leverage for actuating the feeding mechanism in one'direction but will "have -a short leverage when moving said mechanism in the opposite direction.

A further object is the provision of a cani of this character in which a wide variation timing of the advancing and 'returning movements of the feeding mechanism may be varied.

In the accompanying drawings,-

Figure 1 is a side view of `a mechanism embodying the present invention, the mechanism here illustrated being adapted to be connected to a bottle feeding apparatus not shown.

Fig. 2 is a top plan View of the structure shown in'Fig. 1; and

Fig. 3 is an end view thereof. Y

While any suitable supporting structure may be employed, the mechanism is shown in the accompanying drawings as being supported on substantial frame members 10 provided with bearings 11 adjacent one end for a rocker shaft 12 which is journaled therein. The frame members 10 are spaced apart by suitable cross pieces and the rocker shaft12 extends transversely of the frame with its ends projectingV a short distance beyond the outer sides of the frame for a purpose presently to be described.

Mounted on the rocker shaft 12 intermediate tlie frame members 10 and keyed nary Specification of Letters Patent. Patented hzty 2, 1922., Application filed May 25, 1921. vSerial No. 472,337. A i

` their upper ends being connected kto the feeding mechanism to beoplerated by an 'adjustable link connection 1 1 rJournaled in bearings 19 approximately midway the ends of the frame members 10 is a shaft 20 adapted to be rotated by ordidriven from any-suitable source vof power. Mounted on shaft 20 is an actuator arm having its -outer free end provided with bearings yfor a cam roller 25, the arm' and j worm reduction gearing 21 connected 'by a shaftv22 carrying a pulley 23 which is roller'being adapted to be revolved in the f direction indicated by the arrow through the driving connections just described. j

Cam arm 15 is comparatively long, eX-

'tending below the fiamejmembers10 and beyond the actuatory arm shaft 20, and, as

shown, said arm is provided at its endwith arcani surface 26; The rockerlevers- 17 are shown, in Fig.` 1v, in their retracted positions and 'when said arms are in that position, the cam surface 26 of cam arm 15 is positioned in the path of the cam roller 25 Y carried by the revolving actuator armv 24.

As arm 24 continues to revolve, cam arm 15 is depressed until it reaches the position shown in dotted lines in Fig. 1, at which point the cam roller 25 will ride ofi' cam face 26. The curvature of arm 15 is such that said arm will then be free to be elevated to its original position by mechanism hereinafter described, but it is momentarily maintained in its depressed position, while the bottles are being washed, or when any other work to which the machine is adapted is being accomplished, by the rocker levers 17 and a counterbalance 27 formed on the cani 14and projecting on the opposite side' kof cam shaft 12. As the arm15 is being depressed, the rocker shaft 12 is rocked in its bearings and the rocker levers 17 are advanced to the position shown in dotted lines in Fig. 1, as will be understood. Y

Cam arm 16 projects upwardly from cam shaft 12 and when the rocker levers are retracted said arm occupies the position in which it is shown in full lines in Fig. 1,

that is, rwith its cam surfaceQS out of the path traveled bythe revolving actuator arm 24 and cam Wheel 25.V lheii, however, cam arm has been depressed, Yarm 16 is moved f, to the position shown in dotted lines in Fig.

1 and is positioned in the path of the actuator -arm vand cam roller, and lwhen said roller is brought iii` contact with the aim 16, by the revolving actuator arm, said 'camV arm Will be returned or elevated to its former position. This return movement/of arm 16 Will return arm 15 to its elevated position ready to be engaged and depressed by the actuator arm during the next revolution of the latter 'and the rocker levers 17 will also be retracted to their former position.v Y'

Gam arm 16 is considerably shorter than arm 15, the long leverage of arm 15 causing the rocker arms 17 .to be advanced slowly. While the comparatively shortvleverage secured by arm 16 Will retract the rocker arms at a greater rate of speed. The relative lengths of arms 15 and lbeing determinative of the speeds at which the rocker-arms 17 areadvanced and retracted, and it being a simple matter to make the arms of any desired length it is possible to secure any desired variation in the advancing and retracting movements of the rocker levers.

While the present invention has been described in, connection with a milk bottle .Washing machine wherein the bottles, in

traysvor boxes, are advanced under and removed from their lrespective jets, it Will be n understood that the mechanism may be con- Hn.ectedto any feed mechanism that it is desiied to uniformly actuate at'timed inter. l
